Level Order Tree Traversal

Introduction This is the third article in the Tree Traversals - Online Classes. I have written many articles about non-linear data structures and their traversals. But the more you dive in you can find many more ways to traverse a tree. Here we try to solve the level order tree traversal for a binary tree and we will also try to figure out other variations of this traversal. This can we precisely extended for a n-ary tree as well. Defining the problem Let us consider the above tree, if we follow the blue line from root till end and print all the nodes, we will end up printing the lev...
